Two local ready-mix cement manufacturers, Here and There, have combined demand given by Q = 105 − P. Their total costs are given by TC Here = 5 Q Here + 0.5 Q 2Here and TC There = 5 Q There + 0.5 Q 2Here. If they successfully collude, their maximum joint profits will be: $2,500 $2,000 $1,000 $500 $1,600

Why is maximum pipe size advantageous?

Maximum theoretical percent from crystallization when given solubilities in hot and cold water

The solubility of acetanilide in hot water (5.5g/100ml at 100℃) is not very great, and its solubility in cold water (.53g/100ml at 0℃) is still significant. What is the maximum theoretical percent recovery from the crystallization of 5g of acetanilide from 100ml of water (assuming the solution is chilled to 0℃ for filtration).
